Granted: 1997-09-23
Abstract: A mixing valve comprising a modular cartridge non-rotatably mounted in a housing.  The cartridge includes inlet passages in its bottom portion, outlet passages in its top portion, and a pressure balance valve intermediate and in communication with said inlet and outlet passages.  The inlet passages are in communication at their downstream ends with supply ports in the housing.   The outlet passages are in communication at their upstream ends with a volume and temperature control valve plate.  The volume and temperature control valve plate is rotatable to align or misalign outlet apertures in said plate with the outlet passages in the cartridge. The rotation of the plate is controlled by a stem attached to a handle.   Means  are  provided  to  adjust  the  maximum  water temperature.  The temperature adjustment means include an orienting stem ring having an opening shaped to receive a complementary shaped section of the stem.  The orienting stem ring has a splined shaped seat which receives an annular splined section of a hot water stop member.   The hat water stop member also has a stop shoulder which, upon rotation, abuts against a stop flange of the housing cap.

Abstract: A safety device for the roll space within a calender or other roll machine is disclosed. The rolls when rotating, excite oscillations in the beam at the resonant frequency of the beam. This can occur during start-up or during normal operation. The safety device of the present invention comprises a beam and additional mass that is oscillatorily suspended from the beam in order to reduce the amplitude of the beam oscillations at the beam resonant frequency. In addition, a damping element between the additional mass and the beam is used to reduce any undesired oscillations due to newly created resonant frequencies introduced into the system.

Abstract: ABSTRACT        A  portfolio  having  a  detachable  wallet  is described.    The  wallet  can  contain  an  electronic calculating device or a radio.  The wallet is mounted within the portfolio so that the wallet may be opened to a position outside the perimeter of the portfolio, or the wallet may be removed from the portfolio and used separately.  The portfolio contains a pocket adapted to receive the front flap of the wallet so that the wallet can be contained within the portfolio.   In order to secure the wallet within the portfolio,  the wallet contains a pair of closure members, one of which is adapted to mate with a closure member located on the inside of the portfolio.   When the wallet member is detached from the portfolio, the pair of closure members contained on the wallet member mate with each other to secure the wallet member in a closed position detached from  the  portfolio.    Thus,  the  wallet  member is conveniently used and stored with or apart from the portfolio.

Granted: 2007-01-23
Abstract: A water reservoir is provided for a refrigerator. The reservoir is formed as an elongated tubular member bent into a single U-shape with the tubular member having a constant cross section along its length and a constant vertical rise along its length from an inlet to an outlet. The two legs angle upwardly at a common slope and the legs are substantially the same length so that the inlet and outlet are adjacent to one another. The reservoir thus forms a compact shape which fits into a previously unused space behind a crisper drawer within the refrigerator compartment.

Title: Structure of automobile exterior rearview mirror
Inventor: LIN CHUNG-MOU
IPC: B60R1/08
Filed: 1995-03-16
Granted: 2001-02-20
Abstract: A new structure of automobile exterior rearview mirror which integrates an arc-surface wide-angle mirror and a plane mirror together to form a one-piece design.   This design overcomes the drawbacks of the existing exterior rearview mirror,  in which a driver use a stick-on type wide-angle mirror.  In addition, the present invention also provides a blank surface area with parabolized image coating.  The blank surface area is formed between the wide-angle mirror and the plane mirror and its function is to prevent the refraction and reflection interferences caused by the wide-angle mirror and the plane mirror.  The exterior rearview mirror of the present invention is economical, will not fall off and has no blind spot.  It is a full view safety mirror for backing up the car, making turns and changing lanes in the roadway.

Title: Production de signaux optiques au moyen de composants haute frequence

IPC: H04B10/508

Granted: 2000-03-21
Abstract: Un faisceau optique à modulation HF élevée est produit à la sortie (10) en générant dans la source (4a) une modulation à basse fréquence utilisée pour commander la sortie optique (9) d'un laser (1) puis en modulant ladite sortie optique (3) dans un modulateur optique (6) à l'aide d'un signal de commande présentant une modulation à basse fréquence différente générée par la source (4b). L'une et/ou l'autre des deux modulations à basse fréquence est/sont également porteuse(s) d'une information modulée. L'effet du modulateur optique (6) est de transposer la modulation du faisceau optique par la fréquence de modulation du signal de commande. Le modulateur optique (6) peut consister en un interféromètre de Mach-Zehnder. La non-linéarité d'un tel modulateur par rapport à son signal de commande d'entrée peut être exploitée en sélectionnant l'amplitude du signal de commande de façon telle que la sortie optique (3) soit transposée d'un entier multiple de la fréquence de modulation générée par la source (4b). Ces méthodes évitent de devoir appliquer la modulation à haute fréquence à l'entrée du laser (2) et/ou directement à l'entrée de commande (7).

Abstract: Methanol supplied as a raw fuel is mixed with water, vaporized in an evaporator 24, and supplied to a reformer 22 as a raw fuel gas.          The reformer 22 also receives a supply of the compressed air from an air tank 36.  The raw fuel gas is mixed with the compressed air in the reformer 22.  An oxidation reaction of methanol supplied as the raw fuel proceeds in the reformer 22 to generate hydrogen and carbon dioxide,  while a steam reforming reaction of methanol simultaneously proceeds in the reformer 22 to generate hydrogen and carbon dioxide.  The amount of heat required for the endothermic reforming reaction can be supplied by the oxidation reaction of methanol.  No external heat source is accordingly required in the reformer 22 to supply the heat required for the reforming reaction.
